設けてある。In FIG. 2, reference numeral 1 denotes a box-shaped shelf containing a heating element such as a printed wiring board, and a large number of ventilation slits are arranged on the bottom plate 1A and the upper plate 1B of the shelf 1. There is.
それぞれのシェルフ間にファンユニット５を介在させて
シェルフ１を多段に重置し、ファンユニット５でシェル
フ内に収容した印刷配線板を冷却している。The shelves 1 are stacked in multiple stages with the fan units 5 interposed between the shelves, and the fan unit 5 cools the printed wiring boards housed in the shelves.
ファンユニット５は、吸入口を有する正面板７と排出口

前部の吸入ダクト20と斜め後部の排出ダクト10に枠体内
を区画している。The fan unit 5 comprises a front plate 7 having an inlet port, a rear plate 8 having an outlet port, and left and right side plates, and a shield plate 9 which is inclined downward to the front and is installed in the frame body. The frame body is partitioned into an intake duct 20 and an obliquely rearward exhaust duct 10.
そして、この排出ダクト10の下部に、複数のファンを平
面視で格子状に配列させてある。A plurality of fans are arranged in a lattice pattern in a plan view below the exhaust duct 10.
詳細すると第２図（ｂ）に示すように、ファンは、前列
6-1に３基のファン6-1a,6-1b,6-1cが配列し、後列6-2に
３基のファン6-2a,6-2b,6-2cが配列している。In detail, as shown in FIG. 2 (b), the fans are arranged in the front row.
Three fans 6-1a, 6-1b, 6-1c are arranged in 6-1 and three fans 6-2a, 6-2b, 6-2c are arranged in the rear row 6-2.
したがって、それぞれのファンユニット５を駆動する

方に上昇し後面板８の排出口をから機器後方へ排出され
る。Therefore, when each fan unit 5 is driven, cool air is sucked into the shelf 1 through the intake duct 20 and the ventilation slits of the bottom plate 1A from the inlet of the front plate 7 of the lower fan unit 5 of the shelf 1, and the shelf 1 The heat of the printed wiring board housed inside is taken away and it rises as warm air and rises.
After passing through the ventilation slit 4 of 1B and the fan of the upper fan unit 5, it enters the discharge duct 10, rises obliquely upward along the shield plate 9, and is discharged from the discharge port of the rear face plate 8 to the rear of the device.
上記ファンユニットは、ファンを前列と後列との２列に
配列し、且つファン列の上方に前下がりに傾斜した遮蔽
板を設け、それぞれのファンが真っ直ぐ上方に吐出する
空気を、遮蔽板で斜め上方に変針させ機器の外に排出さ
せる構造である。The fan unit has fans arranged in two rows, a front row and a rear row, and a shielding plate inclined downward to the front is provided above the row of fans, and the air discharged by each fan is directed upward by the shielding plate. It is a structure in which the needle is changed upward and discharged outside the device.
したがって、排出口に近い後列のファンが吐出する空気
の上昇流が、排出口から遠い前列のファンから吐出され
遮蔽板に沿って斜め上後方に流れる空気の流れを妨害す
る。Therefore, the ascending flow of the air discharged by the fans in the rear row close to the outlet obstructs the flow of the air discharged from the fans in the front row far from the outlet and flowing obliquely upward and rearward along the shield plate.
このために、排出ダクト10内の直列のファンの上方に空
気が滞りその部分の圧力が上昇する。For this reason, air is trapped above the series of fans in the exhaust duct 10 and the pressure in that portion rises.
したがって、前列のファンの回転数が低くなり、前列の
ファンが吐出する空気量が低下し、シェルフの前部に収
容した発熱体の冷却が不充分になるという問題点があっ
た。Therefore, the number of rotations of the fans in the front row is reduced, the amount of air discharged by the fans in the front row is reduced, and the heating elements housed in the front portion of the shelf are insufficiently cooled.
本考案はこのような点に鑑みて創作されたもので、それ
ぞれのシェルフ内に収容した発熱体を、むら無く冷却し
